Received ; revised manuscript received We have studied pp annihilations at rest in liquid hydrogen into the nal state ! 0 where ! decays to 0. This reaction is dominated by the production of a 0 (980) and contributions from a 2 (1320) and b 0 1 (1235). Upper limits for the production of an axial vector h 0 1 (1380) meson and vector mesons !(1390), !(1600),(More)
The Crystal Barrel Collaboration ABSTRACT Recent observations by the Crystal Barrel experiment of two scalar resonances, f 0 (1365) and a 0 (1450) have allowed us to clarify the members of the scalar nonet. These states replace the f 0 (950) and a 0 (980). In addition, a third scalar, f 0 (1500), appears to be supernumerary and its apparent avor{blind(More)
